A companion to the PALS Production Guides for Strawberries, Raspberries and Blueberries.

Please note: Due to budgetary constraints, the 2014 Cornell Pest Management Guidelines for Berry Crops will not be available online. The Cornell Pest Management Education Program (PMEP) that produces the various crop pest management guidelines is currently exploring options that will allow them to recover the costs of posting these publications online. They hope to have the guideline series back online in 2015. Meanwhile print copies may be purchased through your local Cornell Cooperative Extension office or the Cornell Store at Cornell University (800.624.4080 or online). Questions or comments? Send an email to PMEP_Webmaster@cornell.edu.

Much information exists on controlling plant pests and problems, but one must first identify the
cause before intervention can occur. This diagnostic tool was developed to assist the student, grower,
and extension educator in identifying potential causes of plant problems in berry crops.

The blackberry diagnostic tool was developed by Dr. Gina Fernandez, North Carolina State University.

The ribes (currant and gooseberry) diagnostic tool was developed by Dr. Kim Hummer, National Germplasm
Repository at Corvallis, Oregon.

Photographs used in the diagnostic tool are owned by others, and are for educational purposes only. They are not to be used for any commercial purpose, or reproduced in any way,
without permission from PALS or the photographers (where indicated).
